“…With the huge volume requirements of the hydrogen fuel tanks, aircraft design needs to be modified with a greater volume and heavier fuselage, which is the best location to place LH2 fuel tanks, as shown in Figure 1 [23]. For short-to-medium range aircraft, the hydrogen tanks could be placed above the passenger cabin while for the long-range aircrafts the hydrogen is stored in two big integral tanks; one of them is located directly behind the cockpit and the second is placed at the far aft of the passenger cabin [30]. The configuration of hydrogen tanks has a significant impact on the energy efficiency of hydrogen-powered aircraft [30].…”

The configuration of hydrogen tanks has a significant impact on the energy efficiency of hydrogen-powered aircraft [30]. The top-tank design, used in short-tomedium range aircraft, may increase the energy use by 6-19% due to the greater weight of this type of tanks [30].…”

The world energy consumption is greatly influenced by the aviation industry with a total energy consumption ranging between 2.5% and 5%. Currently, liquid fossil fuel, which releases various types of Greenhouse Gas (GHG) emissions, is the main fuel in the aviation industry. As the aviation industry grows rapidly to meet the requirements of the increased world population, the demand for environmentally friendly power technology for various applications in the aviation sector has been increased sharply in recent years. Among the various clean power sources, energy obtained from hydrogen is considered the future for energy generation in the aviation industry due to its cleanness and abundance. This paper aims to give an overview of the potential aviation applications where hydrogen and fuel cell technology can be used. Also, the major challenges that limit the wide adoption of hydrogen technology in aviation are highlighted and future research prospects are identified.

“…In [18], a comparison of hydrogen with hydrocarbon fuels for aviation is discussed. Further discussion of hydrogen utilization for aircraft engines is given for instance in [19][20][21][22][23][24][25][26][27]. A good review with respect to hydrogen in aviation is given specifically by Cecere et al [28].…”

Abstract:With the growth of aviation traffic and the demand for emission reduction, alternative fuels like the so-called electrofuels could comprise a sustainable solution. Electrofuels are understood as those that use renewable energy for fuel synthesis and that are carbon-neutral with respect to greenhouse gas emission. In this study, five potential electrofuels are discussed with respect to the potential application as aviation fuels, being n-octane, methanol, methane, hydrogen and ammonia, and compared to conventional Jet A-1 fuel. Three important aspects are illuminated. Firstly, the synthesis process of the electrofuel is described with its technological paths, its energy efficiency and the maturity or research need of the production. Secondly, the physico-chemical properties are compared with respect to specific energy, energy density, as well as those properties relevant to the combustion of the fuels, i.e., autoignition delay time, adiabatic flame temperature, laminar flame speed and extinction strain rate. Results show that the physical and combustion properties significantly differ from jet fuel, except for n-octane. The results describe how the different electrofuels perform with respect to important aspects such as fuel and air mass flow rates. In addition, the results help determine mixture properties of the exhaust gas for each electrofuel. Thirdly, a turbine configuration is investigated at a constant operating point to further analyze the drop-in potential of electrofuels in aircraft engines. It is found that electrofuels can generally substitute conventional kerosene-based fuels, but have some downsides in the form of higher structural loads and potentially lower efficiencies. Finally, a preliminary comparative evaluation matrix is developed. It contains specifically those fields for the different proposed electrofuels where special challenges and problematic points are seen that need more research for potential application. Synthetically-produced n-octane is seen as a potential candidate for a future electrofuel where even a drop-in capability is given. For the other fuels, more issues need further research to allow the application as electrofuels in aviation. Specifically interesting could be the combination of hydrogen with ammonia in the far future; however, the research is just at the beginning stage.

Hydrogen is a clean fuel that can be used as the major energy resource. Hydrogen can be produced from various renewable and sustainable sources. Cost of hydrogen is high when it is produced from alternative sources. Hydrogen can be utilized as an energy source when it can be produced from cheap and renewable source. Emphasis should be given to those methods that have a low CO 2 footprint. Purification, transportation, and storing are important aspects that can be emphasized. Hydrogen is used as fuel in internal combustion engine ( ICE ) and fuel cell electric vehicle ( FCEV ). The cost of FCEV is higher than car with ICE . However, the FCEVs have more fuel efficiency than ICE car. Suitable materials should be developed for storing hydrogen in both liquid and compressed gas form. Lightweight, high mechanical strength, and low‐cost materials are preferred for this purpose. Safety issues should be taken care for production, fueling, and transportation systems.
